DeKALB – A 29-year-old Tinley Park man was arrested Tuesday after police found guns and body armor in his dorm room at Northern Illinois University's New Hall West.

A worker sorting mail at the residence hall called police after she found a package containing gun parts from Primary Arms addressed to Kevin Ouwenga, court records show. NIU police searched Ouwenga's room and found a dissassembled AR-15 rifle, a .40-caliber Glock handgun, along with ammunition for both and body armor inside, court records show.

Ouwenga, who has a valid firearm owners identification card, was charged with unlawful use of a weapon and unlawful possession of a stored weapon. If convicted of the more serious charge, Ouwenga could be sentenced to up to five years in prison.
